Kool Herc...birth name Clive Cambell moved to the Bronx , NY from Jamaica in 1967 at the age of 12 . 6 years later in 1973 he was asked by his sister to Dj a birthday party at a spot called the Twilight Zone . This was his first jam . Herc is the man who took the Jamaican art of toasting......talking in rhyme over the instrumental parts of a record , and made it a main stay in the Bronx . He was known for having the biggest mobile sound system in New York . He would take a hot jam like James Browns " Give it up or turn it loose " and summon the crowd to " Hip Hop and don't stop " ...things of that nature.   Herc was amongst the first (after Pete Dj Jones) to take two copies of a record and manipulate them , so that the drum breakdown played continuously .Along with Klark Kent ,Coke La Rock and Timmy Tim (the Herculords) Herc rocked spots like the PAL ,Celeb Club, Stardust Ballroom , Hoe Ave Boys Club , Harlem World and Black Door. He is part of the Hip Hop holy trinity - which includes Bambaataa and  Flash  . His voice has been on record only once  , on Terminator Xs "Godfathers Of Threatt " Lp . Herc had a small part playing himself in the movie Beat Street .  He can be seen on the cover of the Executioners new Lp "Built From Scratch" with D.ST & Theodore .
